Answer:
Since there is 10% off of the price, the new cost is 90% of the original. So we just multiply the price by 0.9
Answer:
The Range is the difference between the lowest and highest values.
Explanation:
Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.
The answer is letter C. symmetric
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:
(x + 8) x 2 = x - 11
Then, solve:
2x + 16 = x - 11
2x = x -27
x = -27
This can then be checked by using the number in the original text.
-27 + 8 = -19
-19 x 2 = -38
-38 is 11 less than -27.
Hope this helps :)
